I think one way to compromise this is write a help wraper that do not call
browser. Here is the demo:
> cat help.fish
function help
eval "$argv" --help
end
But is can cause errors:

fish: Could not locate end of block. The “end” command is missing,
misspelled or a “;” is missing.
/home/grissiom/My_projects/local-etc/shells/fish/functions/help.fish
(line 3): if --help
^
in . (source) call of file “-”,

“/home/grissiom/My_projects/local-etc/shells/fish/functions/help.fish”,

if - conditionally execute a command
Synopsis
if CONDITION; COMMANDS_TRUE...; [else; COMMANDS_FALSE...;] end
Description
if will execute the command CONDITION. If the condition's exit status
is 0, the commands COMMANDS_TRUE will execute. If the exit status is
not 0 and else is given, COMMANDS_FALSE will be executed.
In order to use the exit status of multiple commands as the condition
of an if block, use begin; ...; end and the short circuit commands and
and or.
The exit status of the last foreground command to exit can always be
accessed using the $status variable.
Example
if test -f foo.txt
echo foo.txt exists
else
echo foo.txt does not exist
end
will print foo.txt exists if the file foo.txt exists and is a regular
file, otherwise it will print foo.txt does not exist.
.: Error while reading file “<stdin>”
So...
